FIELD OF THE INVENTION

The present invention relates to detergent compositions comprising novel DNase variants exhibiting alterations relative to the parent DNase in one or more properties including: wash performance, detergent stability and/or storage stability. The compositions of the invention are suitable for use in cleaning processes and detergent compositions, such as laundry compositions and dish wash compositions, including hand wash and automatic dish washing compositions. The present invention also relates to methods of making detergent compositions and methods of washing and using such DNase variants in surface treatment, particularly fabric treatment and cleaning.

BACKGROUND OF THE INVENTION

Hard surfaces and fabrics are exposed to soils and microorganisms from the environment and from body soils. Soils depositing on such surfaces may exacerbate adhesion of microorganisms and consequently the formation of soils of microbial origin, for example biofilm soils. Biofilms comprise a matrix of extracellular polymeric substance (EPS): a polymeric conglomeration generally comprising extracellular DNA, proteins, and polysaccharides. These soils are sticky, difficult to remove and cause further adhesion of other soils. Thus, house hold care-related soiling is complex and may comprise particulates, protein, starch, grease and also EPS. Consequently, stain removal is also complex and a variety of enzymes may be useful, including deoxyribonuclease (DNase) enzymes.

To be useful in household cleaning processes an enzyme such as a DNase needs to be stable in detergent compositions and compatible with standard detergent components such as surfactants, builders, bleaches etc. The present invention provides detergent compositions comprising such enzymes to provide good cleaning. The invention may also have a benefit in improving cleanliness of laundry and dish-washing machines.

The term “adjunct” means any liquid, solid or gaseous material selected for the particular type of detergent composition desired and the form of the product (e.g., liquid, granule, powder, bar, paste, spray, unit dose, such as tablet or pouch, gel, or foam composition), which materials are also preferably compatible with the DNase variant enzyme used in the composition. In some aspects, granular compositions are in “compact” form, while in other aspects, the liquid compositions are in a “concentrated” form.

The term “allelic variant” means any of two or more alternative forms of a gene occupying the same chromosomal locus. Allelic variation arises naturally through mutation, and may result in polymorphism within populations. Gene mutations can be silent (no change in the encoded polypeptide) or may encode polypeptides having altered amino acid sequences. An allelic variant of a polypeptide is a polypeptide encoded by an allelic variant of a gene.

“Biofilm” is a soil of microbial origin which may be produced by any group of microorganisms and typically comprises a self-produced matrix of extracellular polymeric substance (EPS). Biofilm EPS is a polymeric conglomeration generally composed of extracellular DNA, proteins, and polysaccharides. Biofilm-producing bacteria include for example, the following species: Acinetobacter sp., Aeromicrobium sp., Brevundimonas sp., Microbacterium sp., Micrococcus luteus, Pseudomonas sp., Staphylococcus epidermidis, and Stenotrophomonas sp.

The term “cDNA” means a DNA molecule that can be prepared by reverse transcription from a mature, spliced, mRNA molecule obtained from a prokaryotic or eukaryotic cell. A cDNA lacks intron sequences that may be present in the corresponding genomic DNA. The initial, primary RNA transcript is a precursor to mRNA that is processed through a series of steps, including splicing, before appearing as mature spliced mRNA.

The term “clade” means a group of polypeptides clustered together based on homologous features traced to a common ancestor. Polypeptide clades can be visualized as phylogenetic trees and a clade is a group of polypeptides that consists of a common ancestor and all its lineal descendants. Polypeptides forming a group e.g. a clade as shown in a phylogenetic tree may often share common properties and are more closely related than other polypeptides not in the clade.

The term “coding sequence” means a polynucleotide, which directly specifies the amino acid sequence of its polypeptide product. The boundaries of the coding sequence are generally determined by an open reading frame, which usually begins with the ATG start codon or alternative start codons such as GTG and TTG and ends with a stop codon such as TAA, TAG, and TGA. The coding sequence may be a DNA, cDNA, synthetic, or recombinant polynucleotide.

The term “control sequences” means all components necessary for the expression of a polynucleotide encoding a variant of the present invention. Each control sequence may be native or foreign to the polynucleotide encoding the variant or native or foreign to each other.

Such improved properties include, but are not limited to, stability, such as detergent stability, wash performance e.g. deep cleaning effect and the deep-cleaning effect may include but is not limited to de-gluing effect.

The term “improved DNase activity” is defined herein as an altered DNase activity e.g. by increased catalysis of hydrolytic cleavage of phosphodiester linkages in the DNA the DNase variant displaying an alteration of the activity relative (or compared) to the activity of the parent DNase, such as compared to a DNase with SEQ ID NO: 1, SEQ ID NO: 27 or SEQ ID NO: 28.

The term “low detergent concentration” system includes detergents where less than about 800 ppm of detergent components is present in the wash water. Asian, e.g., Japanese detergents are typically considered low detergent concentration systems.

The term “improved wash performance” includes but is not limited to the term “deep cleaning effect”. Improved performance e.g. deep cleaning performance of a DNase variant according to the invention is measured compared to the DNase parent e.g. the DNase shown in SEQ ID NO: 1, SEQ ID NO: 27 or SEQ ID NO: 28. The improved performance e.g. cleaning or deep cleaning performance may be expressed as a Remission value of the stained swatches.

Conventions for Designation of Variants

For purposes of the present invention, unless otherwise indicated the polypeptide disclosed in SEQ ID NO: 1 is used to determine the corresponding amino acid residue in another DNase. The amino acid sequence of another DNase is aligned with the polypeptide disclosed in SEQ ID NO: 1, and based on the alignment, the amino acid position number corresponding to any amino acid residue in the polypeptide disclosed in SEQ ID NO: 1 is determined using e.g. the Needleman-Wunsch algorithm (Needleman and Wunsch, 1970, J. Mol. Biol. 48: 443-453) as implemented in the Needle program of the EMBOSS package (EMBOSS: The European Molecular Biology Open Software Suite, Rice et al., 2000, Trends Genet. 16: 276-277), preferably version 5.0.0 or later. The parameters used are gap open penalty of 10, gap extension penalty of 0.5, and the EBLOSUM62 (EMBOSS version of BLOSUM62) substitution matrix.

Identification of the corresponding amino acid residue in another DNase can be determined by an alignment of multiple polypeptide sequences using several computer programs including, but not limited to, MUSCLE (multiple sequence comparison by log-expectation; version 3.5 or later; Edgar, 2004, Nucleic Acids Research 32: 1792-1797), MAFFT (version 6.857 or later; Katoh and Kuma, 2002, Nucleic Acids Research 30: 3059-3066; Katoh et al., 2005, Nucleic Acids Research 33: 511-518; Katoh and Toh, 2007, Bioinformatics 23: 372-374; Katoh et al., 2009, Methods in Molecular Biology 53709-64; Katoh and Toh, 2010, Bioinformatics 26:1899-1900), and EMBOSS EMMA employing ClustalW (1.83 or later; Thompson et al., 1994, Nucleic Acids Research 22: 4673-4680), using their respective default parameters.

When the another enzyme has diverged from the polypeptide of SEQ ID NO: 1 such that traditional sequence-based comparison fails to detect their relationship (Lindahl and Elofsson, 2000, J. Mol. Biol. 295: 613-615), other pairwise sequence comparison algorithms can be used. Greater sensitivity in sequence-based searching can be attained using search programs that utilize probabilistic representations of polypeptide families (profiles) to search databases. For example, the PSI-BLAST program generates profiles through an iterative database search process and is capable of detecting remote homologs (Atschul et al., 1997, Nucleic Acids Res. 25: 3389-3402). Even greater sensitivity can be achieved if the family or superfamily for the polypeptide has one or more representatives in the protein structure databases. Programs such as GenTHREADER (Jones, 1999, J. Mol. Biol. 287: 797-815; McGuffin and Jones, 2003, Bioinformatics 19: 874-881) utilize information from a variety of sources (PSI-BLAST, secondary structure prediction, structural alignment profiles, and solvation potentials) as input to a neural network that predicts the structural fold for a query sequence. Similarly, the method of Gough et al., 2000, J. Mol. Biol. 313: 903-919, can be used to align a sequence of unknown structure with the superfamily models present in the SCOP database. These alignments can in turn be used to generate homology models for the polypeptide, and such models can be assessed for accuracy using a variety of tools developed for that purpose.

For proteins of known structure, several tools and resources are available for retrieving and generating structural alignments. For example, the SCOP super families of proteins have been structurally aligned, and those alignments are accessible and downloadable. Two or more protein structures can be aligned using a variety of algorithms such as the distance alignment matrix (Holm and Sander, 1998, Proteins 33: 88-96) or combinatorial extension (Shindyalov and Bourne, 1998, Protein Engineering 11: 739-747), and implementation of these algorithms can additionally be utilized to query structure databases with a structure of interest in order to discover possible structural homologs (e.g., Holm and Park, 2000, Bioinformatics 16: 566-567).

As different amino acids may be present at a given position depending on the selected parent for the variants the amino acid positions are indicated with #₁, #₂, etc. in the definitions below. In describing the variants of the present invention, the nomenclature described below is adapted for ease of reference. The accepted IUPAC single letter or three letters amino acid abbreviations are employed. Amino acid positions are indicated with #₁, #₂, etc.

Substitutions: For an amino acid substitution, the following nomenclature is used: Original amino acid, position, substituted amino acid. Accordingly, the substitution of valine at position #1 with alanine is designated as “Val#₁Ala” or “V#₁A”. Multiple mutations are separated by addition marks (“+”) or by commas (,), e.g., “Val#₁Ala+“Pro#₂Gly” or V#₁A, P#₂G, representing substitutions at positions #₁ and #₂ of valine (V) and proline (P) with alanine (A) and glycine (G), respectively. If more than one amino acid may be substituted in a given position these are listed in brackets, such as [X] or {X}. Thus, if both Trp and Lys may be substituted instead of the amino acid occupying at position #₁ this is indicated as X#₁ {W, K}, X#₁ [W, K] or X#₁ [W/K], where the X indicate the amino acid residue present at the position of the parent DNase e.g. such as a DNase shown in SEQ ID NO: 1 or a DNase having at least 60% identity hereto. In some cases the variants may be represented as #₁ {W, K} or X#₂P indicating that the amino acids to be substituted vary depending on the parent. For convenience, as SEQ ID NO: 1 is used for numbering the substitutions, the amino acid in the corresponding position in SEQ ID NO: 1 is indicated, e.g. T1A. However, it will be clear to the skilled artisan that a DNase variant comprising T1A is not limited to parent DNases having threonine at a position corresponding to position 1 of SEQ ID NO: 1. In a parent DNase having e.g. asparagine in position 1, the skilled person would translate the mutation specified as T1A to N1A. In the event the parent DNase has alanine in position 1, the skilled person would recognize that the parent DNase is not changed at this position. The same applies for deletions and insertions described below. Herein, unless otherwise indicated, numbering is according to SEQ ID NO: 1.

Deletions: For an amino acid deletion, the following nomenclature is used: Original amino acid, position, *. Accordingly, the deletion of valine at position #₁ is designated as “Val#₁*” or “V#₁*”. Multiple deletions are separated by addition marks (“+”) or commas, e.g., “Val#₁*+Pro#₂*” or “V#₁*, P#₂*”.

Insertions: The insertion of an additional amino acid residue such as e.g. a lysine after Val#₁ may be indicated by: Val#₁ValLys or V#₁VK. Alternatively insertion of an additional amino acid residue such as lysine after V#₁ may be indicated by: *#₁aK. When more than one amino acid residue is inserted, such as e.g. a Lys, and Gly after #₁ this may be indicated as: Val#₁ValLysGly or WO/KG. In such cases, the inserted amino acid residue(s) may also be numbered by the addition of lower case letters to the position number of the amino acid residue preceding the inserted amino acid residue(s), in this example: *#₁aK *#₁bG.

Multiple alterations: Variants comprising multiple alterations are separated by addition marks (“+”) or by commas (,), e.g., “Val#₁Trp+Pro#₂Gly” or “V#₁W, P#₂G” representing a substitution of valine and proline at positions #₁ and #₂ with tryptophan and glycine, respectively as described above.

Different alterations: Where different alterations can be introduced at a position, the different alterations may be separated by a comma, e.g., “Val#₁Trp, Lys” or V#₁W, K representing a substitution of valine at position #₁ with tryptophan or lysine. Thus, “Val#₁Trp, Lys+Pro#₂Asp” designates the following variants: “Val#₁Trp+Pro#₂Asp”, “Val#₁Lys+Pro#₂Asp” or V#₁W, K+P#₂D.

Specific for Nomenclature of Clades

For purposes of the present invention, the nomenclature [IV] or [UV] means that the amino acid at this position may be isoleucine (Ile, I) or valine (Val, V). Likewise, the nomenclature [LVI] and [L/V/I] means that the amino acid at this position may be a leucine (Leu, L), valine (Val, V) or isoleucine (Ile, I), and so forth for other combinations as described herein. Unless otherwise limited further, the amino acid X is defined such that it may be any of the 20 natural amino acids.

The substitutions improve stability in liquid solutions such as cleaning compositions without compromising the wash performance in cleaning processes e.g. laundry. Predicting from the primary sequence of an enzyme, which positions may be altered to obtain an improved effect requires inventive skills, the molecule must be carefully evaluated from structural as well as functional aspects. The present invention relates to detergent compositions comprising variants of DNase enzymes, which has at least one improved property compared to the outset DNase i.e. the parent DNase. The inventors, have identified positions where a the single substitutions provide a stabilising effect and further identified that adding a substitution in more than one of the positions selected from the group consisting of: 1, 4, 7, 8, 9, 13, 22, 25, 27, 32, 33, 39, 41, 42, 48, 56, 57, 59, 61, 65, 66, 76, 77, 78, 91, 101, 106, 109, 112, 116, 127, 130, 138, 140, 144, 147, 148, 154, 157, 159, 160, 162, 166, 167, 174, 175, 177, 178, 179, 180 and 181 provides improved stability importantly without impairing the cleaning performance of the DNase (the ability to remove DNA stains from textiles). One aspect of the invention relates to detergent compositions comprising a variant in which a substitution in more than one position selected from the group consisting of: 1, 4, 7, 8, 9, 13, 22, 25, 27, 32, 33, 39, 41, 42, 48, 56, 57, 59, 61, 65, 66, 76, 77, 78, 91, 101, 106, 109, 112, 116, 127, 130, 138, 140, 144, 147, 148, 154, 157, 159, 160, 162, 166, 167, 174, 175, 177, 178, 179, 180 and 181 is introduced for improving the stabilization effect even further. A detergent composition preferably comprises a DNase variant comprising a substitution at one, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen, twenty or more positions selected from the list consisting of: 1, 4, 7, 8, 9, 13, 22, 25, 27, 32, 33, 39, 41, 42, 48, 56, 57, 59, 61, 65, 66, 76, 77, 78, 91, 101, 106, 109, 112, 116, 127, 130, 138, 140, 144, 147, 148, 154, 157, 159, 160, 162, 166, 167, 174, 175, 177, 178, 179, 180 and 181, wherein each position corresponds to the position of the polypeptide of SEQ ID NO: 1, wherein the variant has DNase activity and wherein the variant has at least 80%, such as at least 85%, such as at least 90%, such as at least 95%, such as at least 98% but less than 100% sequence identity to SEQ ID NO: 1. It is not trivial that substituting at more than one positions would lead to an additive or even synergistic effect as shown in the present invention. An additive effect could not be predicted as adding a substitution to an enzyme may also impact the stability negatively compared to the enzyme with just one substition as the specific combination of substitutions may lead to different results. A preferred embodiment of the invention relates a composition comprising a DNase variant comprising a substitution of an amino acid in at least three, four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen, twenty or more positions selected from the list consisting of: positions selected from the list consisting of: 1, 4, 7, 8, 9, 13, 22, 25, 27, 32, 33, 39, 41, 42, 48, 56, 57, 59, 61, 65, 66, 76, 77, 78, 91, 101, 106, 109, 112, 116, 127, 130, 138, 140, 144, 147, 148, 154, 157, 159, 160, 162, 166, 167, 174, 175, 177, 178, 179, 180 and 181, wherein each position corresponds to the position of the polypeptide of SEQ ID NO: 1, wherein the variants has DNase activity and wherein the variant has at least 80%, such as at least 85%, such as at least 90%, such as at least 95%, such as at least 98% but less than 100% sequence identity to SEQ ID NO: 1.

The variants useful in the present invention may comprise additional mutations to the ones listed above. These additional modifications should preferably not significantly change the improved properties of the variant DNase e.g conservative substitutions.

Examples of conservative substitutions are within the groups of basic amino acids (arginine, lysine and histidine), acidic amino acids (glutamic acid and aspartic acid), polar amino acids (glutamine and asparagine), hydrophobic amino acids (leucine, isoleucine and valine), aromatic amino acids (phenylalanine, tryptophan and tyrosine), and small amino acids (glycine, alanine, serine, threonine and methionine) Amino acid substitutions that do not generally alter specific activity are known in the art and are described, for example, by H. Neurath and R. L. Hill, 1979, In, The Proteins, Academic Press, New York. Common substitutions are Ala/Ser, Val/Ile, Asp/Glu, Thr/Ser, Ala/Gly, Ala/Thr, Ser/Asn, Ala/Val, Ser/Gly, Tyr/Phe, Ala/Pro, Lys/Arg, Asp/Asn, Leu/Ile, Leu/Val, Ala/Glu, and Asp/Gly.

Essential amino acids in a polypeptide can be identified according to procedures known in the art, such as site-directed mutagenesis or alanine-scanning mutagenesis (Cunningham and Wells, 1989, Science 244: 1081-1085). In the latter technique, single alanine mutations are introduced at every residue in the molecule, and the resultant mutant molecules are tested for DNase activity to identify amino acid residues that are critical to the activity of the molecule. See also, Hilton et al., 1996, J. Biol. Chem. 271: 4699-4708. The active site of the enzyme or other biological interaction can also be determined by physical analysis of structure, as determined by such techniques as nuclear magnetic resonance, crystallography, electron diffraction, or photoaffinity labeling, in conjunction with mutation of putative contact site amino acids. See, for example, de Vos et al., 1992, Science 255: 306-312; Smith et al., 1992, J. Mol. Biol. 224: 899-904; Wlodaver et al., 1992, FEBS Lett. 309: 59-64.

Polypeptides having DNase activity and which comprise the GYS-clade motifs have shown particularly good deep cleaning properties e.g. the DNases are particularly effective in removing or reducing components of organic matter, such as biofilm components, from an item such as a textile or a hard surface.

Preferably the variant comprises a variant of a DNase parent, wherein the DNase parent belongs to the GYS-clade and wherein the parent DNase comprises one or both motifs [D/M/L][S/T]GYSR[D/N] (SEQ ID NO: 25) or ASXNRSKG (SEQ ID NO: 26).

The parent DNases may be (a) a polypeptide having at least 60% sequence identity to the mature polypeptide of SEQ ID NO: 1, (b) a polypeptide encoded by a polynucleotide that hybridizes under high stringency conditions with the mature polypeptide coding sequence or the full-length complement hereof; or (c) a polypeptide encoded by a polynucleotide having at least 60% sequence identity to the mature polypeptide coding sequence.

The parent preferably has a sequence identity to the polypeptide shown in SEQ ID NO: 1 of at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95%, such as at least 96%, at least 97%, at least 98%, at least 99% or 100% sequence identity to the polypeptide shown in SEQ ID NO: 1, which have DNase activity. It may even be preferred for the parent to comprise or consist of the amino acid sequence of SEQ ID NO: 1.

It may be preferred for the parent to be selected from Bacillus DNases, e.g. a bacillus cibi DNase, e.g., the DNase disclosed herein as SEQ ID NO: 1.

Method of Cleaning

According to the present invention there is also provided a method of treating or cleaning a soiled article or surface such as a soiled hard surface or, preferably fabric. The method comprises (i) contacting the article or surface, preferably a fabric, with an aqueous wash liquor comprising a DNase variant as described herein, and preferably in addition, a detergent composition adjunct; and (ii) optionally rinsing and (iii) drying the surface. The variant and detergent composition adjunct may be added to water separately or, preferably the aqueous wash liquor is formed by adding the detergent composition herein with water to form the aqueous wash liquor.

The article or surface may be contacted with the aqueous wash liquor in a hand washing or machine washing process. Preferably contact with the aqueous wash liquor is in a wash cycle, most preferably of a washing machine, however for a treatment step contact may be in a rinse step of a washing process.

The pH of the aqueous wash liquor is preferably in the range of 1 or 2 to 11, such as in the range 5.5 to 11, such as in the range of 6 to 10, in the range of 7 to 9 or in the range of 7 to 8.5. The aqueous wash liquor is preferably at a temperature in the range of 5° C. to 95° C., or in the range 10 to 80° C., 10° C. to 70° C., 10° C. to 60° C., 10° C. to 50° C., or in the range of 15° C. to 40° C. or in the range of 20° C. to 30° C.

The concentration of the DNase variant enzyme in the aqueous wash liquor is typically in the range of 0.00004-100 ppm enzyme protein, such as in the range of 0.00008-100, in the range of 0.0001-100, in the range of 0.0002-100, in the range of 0.0004-100, in the range of 0.0008-100, in the range of 0.001-100 ppm enzyme protein, 0.01-100 ppm enzyme protein, preferably 0.05-50 ppm enzyme protein, more preferably 0.1-50 ppm enzyme protein, more preferably 0.1-30 ppm enzyme protein, more preferably 0.5-20 ppm enzyme protein, and most preferably 0.5-10 ppm enzyme protein.

The optional rinsing may be a hand rinsing or machine rinsing step, for example as part of a standard washing or laundering process in an automatic washing machine. Optionally there may be more than one rinsing step. Optional additional cleaning or treatment composition (optionally comprising a DNase enzyme for example as described herein) may be added into a pre-wash step and/or a rinsing step, for example a pre-treat and/or fabric conditioning composition. The drying step may be any standard drying step, for instance for laundry, line or machine drying.

In addition to cleaning, the detergent compositions and methods of the invention may as a second benefit prevent and/or reduce malodor. The present invention may enable reduction of soil redeposition, particularly from the aqueous wash liquor where, as the wash progresses soils are removed from surfaces being cleaned and become suspended in the aqueous wash liquor. Where such sticky soils remain on the surface being cleaned redeposition may be a problem which can be overcome by the detergent compostions and methods of cleaning according to the present invention. The detergent compositions and methods of the present invention comprising DNase variants may provide improved deep-cleaning properties compared to the parent DNase and in some aspects, the present invention reduces stickiness and/or re-deposition. In some aspects, the invention relates to the use of a DNase variant or composition comprising the DNase variant according to the invention for deep cleaning of an item, wherein the item is a fabric or a hard surface.

Further, the invention relates to the use of a DNase variant or composition comprising the DNase variant according to the invention for preventing and/or reducing the adherence of soil to an item. In some aspect, the item is textile. When the soil does not adhere to the item, the item appears cleaner. Thus, the invention further relates to the use of a DNase variant according to the invention for maintaining or improving the whiteness of the item.

The present invention further relates to detergent compositions comprising a DNase variant according to the invention preferably with a detergent adjunct ingredient. The detergent composition comprising a DNase variant according to the invention may be used for deep cleaning of an item, for preventing and/or reducing the stickiness of an item, for pretreating stains on the item, for preventing and/or reducing redeposition of soil during a wash cycle, for preventing and/or reducing adherence of soil to an item, for maintaining or improving the whiteness of an item and/or for preventing and/or reducing malodor from an item.

Some aspect relate to a method of obtaining a DNase variant wherein the parent DNase is obtained from bacillus genus.

The DNase variant is preferably a variant wherein the DNase parent has at least 80%, such as at least 85%, at least 90%, at least 95%, at least 96%, at least 97%, at least 98%, or at least 99% but less than 100% sequence identity to the polypeptide shown in SEQ ID NO: 1.

The variants of the invention may be prepared by procedures such as those mentioned below.

Site-directed mutagenesis is a technique in which one or more (e.g., several) mutations are introduced at one or more defined sites in a polynucleotide encoding the parent.

Site-directed mutagenesis can be accomplished in vitro by PCR involving the use of oligonucleotide primers containing the desired mutation. Site-directed mutagenesis can also be performed in vitro by cassette mutagenesis involving the cleavage by a restriction enzyme at a site in the plasmid comprising a polynucleotide encoding the parent and subsequent ligation of an oligonucleotide containing the mutation in the polynucleotide. Usually the restriction enzyme that digests the plasmid and the oligonucleotide is the same, permitting sticky ends of the plasmid and the insert to ligate to one another. See, e.g., Scherer and Davis, 1979, Proc. Natl. Acad. Sci. USA 76: 4949-4955; and Barton et al., 1990, Nucleic Acids Res. 18: 7349-4966.

Site-directed mutagenesis can also be accomplished in vivo by methods known in the art. See, e.g., U.S. Patent Application Publication No. 2004/0171154; Storici et al., 2001, Nature Biotechnol. 19: 773-776; Kren et al., 1998, Nat. Med. 4: 285-290; and Calissano and Macino, 1996, Fungal Genet. Newslett. 43: 15-16.

Synthetic gene construction entails in vitro synthesis of a designed polynucleotide molecule to encode a polypeptide of interest. Gene synthesis can be performed utilizing several techniques, such as the multiplex microchip-based technology described by Tian et al. (2004, Nature 432: 1050-1054) and similar technologies wherein oligonucleotides are synthesized and assembled upon photo-programmable microfluidic chips.

Single or multiple amino acid substitutions, deletions, and/or insertions can be made and tested using known methods of mutagenesis, recombination, and/or shuffling, followed by a relevant screening procedure, such as those disclosed by Reidhaar-Olson and Sauer, 1988, Science 241: 53-57; Bowie and Sauer, 1989, Proc. Natl. Acad. Sci. USA 86: 2152-2156; WO 95/17413; or WO 95/22625. Other methods that can be used include error-prone PCR, phage display (e.g., Lowman et al., 1991, Biochemistry 30: 10832-10837; U.S. Pat. No. 5,223,409; WO 92/06204) and region-directed mutagenesis (Derbyshire et al., 1986, Gene 46: 145; Ner et al., 1988, DNA 7: 127).

Mutagenesis/shuffling methods can be combined with high-throughput, automated screening methods to detect activity of cloned, mutagenized polypeptides expressed by host cells (Ness et al., 1999, Nature Biotechnology 17: 893-896). Mutagenized DNA molecules that encode active polypeptides can be recovered from the host cells and rapidly sequenced using standard methods in the art. These methods allow the rapid determination of the importance of individual amino acid residues in a polypeptide.

Semi-synthetic gene construction is accomplished by combining aspects of synthetic gene construction, and/or site-directed mutagenesis, and/or random mutagenesis, and/or shuffling. Semi-synthetic construction is typified by a process utilizing polynucleotide fragments that are synthesized, in combination with PCR techniques. Defined regions of genes may thus be synthesized de novo, while other regions may be amplified using site-specific mutagenic primers, while yet other regions may be subjected to error-prone PCR or non-error prone PCR amplification. Polynucleotide subsequences may then be shuffled.

Nucleic Acid Constructs

The nucleic acid constructs comprising a polynucleotide encoding the DNase variants for use in the present invention may be operably linked to one or more control sequences that direct the expression of the coding sequence in a suitable host cell under conditions compatible with the control sequences.

The polynucleotide may be manipulated in a variety of ways to provide for expression of the polypeptide. Manipulation of the polynucleotide prior to its insertion into a vector may be desirable or necessary depending on the expression vector. The techniques for modifying polynucleotides utilizing recombinant DNA methods are well known in the art.

The control sequence may be a promoter, a polynucleotide that is recognized by a host cell for expression of a polynucleotide encoding a polypeptide of the present invention. The promoter contains transcriptional control sequences that mediate the expression of the polypeptide. The promoter may be any polynucleotide that shows transcriptional activity in the host cell including mutant, truncated, and hybrid promoters, and may be obtained from genes encoding extracellular or intracellular polypeptides either homologous or heterologous to the host cell.

Other promoters are described in U.S. Pat. No. 6,011,147.

In a yeast host, useful promoters are obtained from the genes for Saccharomyces cerevisiae enolase (ENO: 1), Saccharomyces cerevisiae galactokinase (GAL1), Saccharomyces cerevisiae alcohol dehydrogenase/glyceraldehyde-3 phosphate dehydrogenase (ADH1, ADH2/GAP), Saccharomyces cerevisiae triose phosphate isomerase (TPI), Saccharomyces cerevisiae metallothionein (CUP1), and Saccharomyces cerevisiae 3 phosphoglycerate kinase. Other useful promoters for yeast host cells are described by Romanos et al., 1992, Yeast 8: 423-488.

The control sequence may also be a transcription terminator, which is recognized by a host cell to terminate transcription. The terminator is operably linked to the 3′ terminus of the polynucleotide encoding the polypeptide. Any terminator that is functional in the host cell may be used in the present invention.

Preferred terminators for bacterial host cells are obtained from the genes for Bacillus clausii alkaline protease (aprH), Bacillus licheniformis alpha-amylase (amyL), and Escherichia coli ribosomal RNA (rrnB).

Preferred terminators for filamentous fungal host cells are obtained from the genes for Bacillus nidulans acetamidase, Bacillus nidulans anthranilate synthase, Bacillus niger glucoamylase, Bacillus niger alpha-glucosidase, Bacillus cibi TAKA amylase, Fusarium oxysporum trypsin-like protease, Trichoderma reesei beta-glucosidase, Trichoderma reesei cellobiohydrolase I, Trichoderma reesei cellobiohydrolase II, Trichoderma reesei endoglucanase Trichoderma reesei endoglucanase II, Trichoderma reesei endoglucanase III, Trichoderma reesei endoglucanase V, Trichoderma reesei xylanase I, Trichoderma reesei xylanase Trichoderma reesei xylanase III, Trichoderma reesei beta-xylosidase, and Trichoderma reesei translation elongation factor.

Preferred terminators for yeast host cells are obtained from the genes for Saccharomyces cerevisiae enolase, Saccharomyces cerevisiae cytochrome C (CYC1), and Saccharomyces cerevisiae glyceraldehyde-3 phosphate dehydrogenase. Other useful terminators for yeast host cells are described by Romanos et al., 1992, supra.

The control sequence may also be an mRNA stabilizer region downstream of a promoter and upstream of the coding sequence of a gene which increases expression of the gene. Examples of suitable mRNA stabilizer regions are obtained from a Bacillus thuringiensis cryIIIA gene (WO 94/25612) and a Bacillus subtilis SP82 gene (Hue et al., 1995, Journal of Bacteriology 177: 3465-3471).

The control sequence may also be a leader, a nontranslated region of an mRNA that is important for translation by the host cell. The leader is operably linked to the 5′ terminus of the polynucleotide encoding the polypeptide. Any leader that is functional in the host cell may be used.

Preferred leaders for filamentous fungal host cells are obtained from the genes for Bacillus cibi TAKA amylase and Bacillus nidulans triose phosphate isomerase.

Suitable leaders for yeast host cells are obtained from the genes for Saccharomyces cerevisiae enolase (ENO: 1), Saccharomyces cerevisiae 3 phosphoglycerate kinase, Saccharomyces cerevisiae alpha-factor, and Saccharomyces cerevisiae alcohol dehydrogenase/glyceraldehyde-3 phosphate dehydrogenase (ADH2/GAP).

The control sequence may also be a polyadenylation sequence, a sequence operably linked to the 3′ terminus of the polynucleotide and, when transcribed, is recognized by the host cell as a signal to add polyadenosine residues to transcribed mRNA. Any polyadenylation sequence that is functional in the host cell may be used.

Preferred polyadenylation sequences for filamentous fungal host cells are obtained from the genes for Bacillus nidulans anthranilate synthase, Bacillus niger glucoamylase, Bacillus niger alpha-glucosidase Bacillus cibi TAKA amylase, and Fusarium oxysporum trypsin-like protease. Useful polyadenylation sequences for yeast host cells are described by Guo and Sherman, 1995, Mol. Cellular Biol. 15: 5983-5990.

The control sequence may also be a signal peptide coding region that encodes a signal peptide linked to the N terminus of a polypeptide and directs the polypeptide into the cell's secretory pathway. The 5′ end of the coding sequence of the polynucleotide may inherently contain a signal peptide coding sequence naturally linked in translation reading frame with the segment of the coding sequence that encodes the polypeptide. Alternatively, the 5′ end of the coding sequence may contain a signal peptide coding sequence that is foreign to the coding sequence. A foreign signal peptide coding sequence may be required where the coding sequence does not naturally contain a signal peptide coding sequence. Alternatively, a foreign signal peptide coding sequence may simply replace the natural signal peptide coding sequence in order to enhance secretion of the polypeptide. However, any signal peptide coding sequence that directs the expressed polypeptide into the secretory pathway of a host cell may be used.

Effective signal peptide coding sequences for bacterial host cells are the signal peptide coding sequences obtained from the genes for Bacillus NCIB 11837 maltogenic amylase, Bacillus licheniformis subtilisin, Bacillus licheniformis beta-lactamase, Bacillus stearothermophilus alpha-amylase, Bacillus stearothermophilus neutral proteases (nprT, nprS, nprM), and Bacillus subtilis prsA. Further signal peptides are described by Simonen and Palva, 1993, Microbiological Reviews 57: 109-137.

Effective signal peptide coding sequences for filamentous fungal host cells are the signal peptide coding sequences obtained from the genes for Bacillus niger neutral amylase, Bacillus niger glucoamylase, Bacillus cibi TAKA amylase, Humicola insolens cellulase, Humicola insolens endoglucanase V, Humicola lanuginosa lipase, and Rhizomucor miehei aspartic proteinase.

Useful signal peptides for yeast host cells are obtained from the genes for Saccharomyces cerevisiae alpha-factor and Saccharomyces cerevisiae invertase. Other useful signal peptide coding sequences are described by Romanos et al., 1992, supra.

The control sequence may also be a propeptide coding sequence that encodes a propeptide positioned at the N terminus of a polypeptide. The resultant polypeptide is known as a proenzyme or propolypeptide (or a zymogen in some cases). A propolypeptide is generally inactive and can be converted to an active polypeptide by catalytic or autocatalytic cleavage of the propeptide from the propolypeptide. The propeptide coding sequence may be obtained from the genes for Bacillus subtilis alkaline protease (aprE), Bacillus subtilis neutral protease (nprT), Myceliophthora thermophila laccase (WO 95/33836), Rhizomucor miehei aspartic proteinase, and Saccharomyces cerevisiae alpha-factor.

Where both signal peptide and propeptide sequences are present, the propeptide sequence is positioned next to the N terminus of a polypeptide and the signal peptide sequence is positioned next to the N terminus of the propeptide sequence.

It may also be desirable to add regulatory sequences that regulate expression of the polypeptide relative to the growth of the host cell. Examples of regulatory sequences are those that cause expression of the gene to be turned on or off in response to a chemical or physical stimulus, including the presence of a regulatory compound. Regulatory sequences in prokaryotic systems include the lac, tac, and trp operator systems. In yeast, the ADH2 system or GAL1 system may be used. In filamentous fungi, the Bacillus niger glucoamylase promoter, Bacillus cibi TAKA alpha-amylase promoter, and Bacillus cibi glucoamylase promoter, Trichoderma reesei cellobiohydrolase I promoter, and Trichoderma reesei cellobiohydrolase II promoter may be used. Other examples of regulatory sequences are those that allow for gene amplification. In eukaryotic systems, these regulatory sequences include the dihydrofolate reductase gene that is amplified in the presence of methotrexate, and the metallothionein genes that are amplified with heavy metals. In these cases, the polynucleotide encoding the polypeptide would be operably linked to the regulatory sequence.

Expression Vectors

This disclosure also relates to recombinant expression vectors comprising a polynucleotide encoding the DNase variants, a promoter, and transcriptional and translational stop signals. The various nucleotide and control sequences may be joined together to produce a recombinant expression vector that may include one or more convenient restriction sites to allow for insertion or substitution of the polynucleotide encoding the polypeptide at such sites. Alternatively, the polynucleotide may be expressed by inserting the polynucleotide or a nucleic acid construct comprising the polynucleotide into an appropriate vector for expression. In creating the expression vector, the coding sequence is located in the vector so that the coding sequence is operably linked with the appropriate control sequences for expression. In a further aspect, polynucleotide sequence codons have been modified by nucleotide substitutions to correspond to the codon usage of the host organism intended for production of the polypeptide of the present invention. The recombinant expression vector may be any vector (e.g., a plasmid or virus) that can be conveniently subjected to recombinant DNA procedures and can bring about expression of the polynucleotide. The choice of the vector will typically depend on the compatibility of the vector with the host cell into which the vector is to be introduced. The vector may be a linear or closed circular plasmid.

The vector may be an autonomously replicating vector, i.e., a vector that exists as an extrachromosomal entity, the replication of which is independent of chromosomal replication, e.g., a plasmid, an extrachromosomal element, a minichromosome, or an artificial chromosome. The vector may contain any means for assuring self-replication. Alternatively, the vector may be one that, when introduced into the host cell, is integrated into the genome and replicated together with the chromosome(s) into which it has been integrated. Furthermore, a single vector or plasmid or two or more vectors or plasmids that together contain the total DNA to be introduced into the genome of the host cell, or a transposon, may be used.

The vector preferably contains one or more selectable markers that permit easy selection of transformed, transfected, transduced, or the like cells. A selectable marker is a gene the product of which provides for biocide or viral resistance, resistance to heavy metals, prototrophy to auxotrophs, and the like.

Examples of bacterial selectable markers are Bacillus licheniformis or Bacillus subtilis dal genes, or markers that confer antibiotic resistance such as ampicillin, chloramphenicol, kanamycin, neomycin, spectinomycin, or tetracycline resistance. Suitable markers for yeast host cells include, but are not limited to, ADE2, HIS3, LEU2, LYS2, METS, TRP1, and URA3. Selectable markers for use in a filamentous fungal host cell include, but are not limited to, adeA (phosphoribosylaminoimidazole-succinocarboxamide synthase), adeB (phosphoribosylaminoimidazole synthase), amdS (acetamidase), argB (ornithine carbamoyltransferase), bar (phosphinothricin acetyltransferase), hph (hygromycin phosphotransferase), niaD (nitrate reductase), pyrG (orotidine-5′ phosphate decarboxylase), sC (sulfate adenyltransferase), and trpC (anthranilate synthase), as well as equivalents thereof. Preferred for use in a Bacillus cell are Bacillus nidulans or Bacillus cibi amdS and pyrG genes and a Streptomyces hygroscopicus bar gene. Preferred for use in a Trichoderma cell are adeA, adeB, amdS, hph, and pyrG genes.

The selectable marker may be a dual selectable marker system as described in WO 2010/039889. In some aspects, the dual selectable marker is an hph-tk dual selectable marker system.

The vector preferably contains an element(s) that permits integration of the vector into the host cell's genome or autonomous replication of the vector in the cell independent of the genome. For integration into the host cell genome, the vector may rely on the polynucleotide's sequence encoding the polypeptide or any other element of the vector for integration into the genome by homologous or non-homologous recombination. Alternatively, the vector may contain additional polynucleotides for directing integration by homologous recombination into the genome of the host cell at a precise location(s) in the chromosome(s). To increase the likelihood of integration at a precise location, the integrational elements should contain a sufficient number of nucleic acids, such as 100 to 10,000 base pairs, 400 to 10,000 base pairs, and 800 to 10,000 base pairs, which have a high degree of sequence identity to the corresponding target sequence to enhance the probability of homologous recombination. The integrational elements may be any sequence that is homologous with the target sequence in the genome of the host cell. Furthermore, the integrational elements may be non-encoding or encoding polynucleotides. On the other hand, the vector may be integrated into the genome of the host cell by non-homologous recombination.

For autonomous replication, the vector may further comprise an origin of replication enabling the vector to replicate autonomously in the host cell in question. The origin of replication may be any plasmid replicator mediating autonomous replication that functions in a cell. The term “origin of replication” or “plasmid replicator” means a polynucleotide that enables a plasmid or vector to replicate in vivo.

Examples of bacterial origins of replication are the origins of replication of plasmids pBR322, pUC19, pACYC177, and pACYC184 permitting replication in E. coli, and pUB110, pE194, pTA1060, and pAMB1 permitting replication in Bacillus.

Examples of origins of replication for use in a yeast host cell are the 2 micron origin of replication, ARS1, ARS4, the combination of ARS1 and CEN3, and the combination of ARS4 and CEN6.

Examples of origins of replication useful in a filamentous fungal cell are AMA1 and ANS1 (Gems et al., 1991, Gene 98: 61-67; Cullen et al., 1987, Nucleic Acids Res. 15: 9163-9175; WO 00/24883). Isolation of the AMA1 gene and construction of plasmids or vectors comprising the gene can be accomplished according to the methods disclosed in WO 00/24883.

More than one copy of a polynucleotide of the present invention may be inserted into a host cell to increase production of a polypeptide. An increase in the copy number of the polynucleotide can be obtained by integrating at least one additional copy of the sequence into the host cell genome or by including an amplifiable selectable marker gene with the polynucleotide where cells containing amplified copies of the selectable marker gene, and thereby additional copies of the polynucleotide, can be selected for by cultivating the cells in the presence of the appropriate selectable agent.

The procedures used to ligate the elements described above to construct the recombinant expression vectors of the present invention are well known to one skilled in the art (see, e.g., Sambrook et al., 1989, supra).

Host Cells

Recombinant host cells comprise a polynucleotide operably linked to one or more control sequences that direct the production of a polypeptide useful in the present invention. A construct or vector comprising a polynucleotide is introduced into a host cell so that the construct or vector is maintained as a chromosomal integrant or as a self-replicating extra-chromosomal vector as described earlier. The term “host cell” encompasses any progeny of a parent cell that is not identical to the parent cell due to mutations that occur during replication. The choice of a host cell will to a large extent depend upon the gene encoding the polypeptide and its source.

The host cell may be any cell useful in the recombinant production of a polypeptide of the present invention, e.g., a prokaryote or a eukaryote.

The prokaryotic host cell may be any Gram-positive or Gram-negative bacterium. Gram-positive bacteria include, but are not limited to, Bacillus, Clostridium, Enterococcus, Geobacillus, Lactobacillus, Lactococcus, Oceanobacillus, Staphylococcus, Streptococcus, and Streptomyces. Gram-negative bacteria include, but are not limited to, Campylobacter, E. coli, Flavobacterium, Fusobacterium, Helicobacter, Ilyobacter, Neisseria, Pseudomonas, Salmonella, and Ureaplasma.

The bacterial host cell may be any Bacillus cell including, but not limited to, Bacillus alkalophilus, Bacillus amyloliquefaciens, Bacillus brevis, Bacillus circulans, Bacillus clausii, Bacillus coagulans, Bacillus firmus, Bacillus lautus, Bacillus lentus, Bacillus licheniformis, Bacillus megaterium, Bacillus pumilus, Bacillus stearothermophilus, Bacillus subtilis, and Bacillus thuringiensis cells.

The bacterial host cell may also be any Streptococcus cell including, but not limited to, Streptococcus equisimilis, Streptococcus pyogenes, Streptococcus uberis, and Streptococcus equi subsp. Zooepidemicus cells.

The bacterial host cell may also be any Streptomyces cell including, but not limited to, Streptomyces achromogenes, Streptomyces avermitilis, Streptomyces coelicolor, Streptomyces griseus, and Streptomyces lividans cells.

The introduction of DNA into a Bacillus cell may be effected by protoplast transformation (see, e.g., Chang and Cohen, 1979, Mol. Gen. Genet. 168: 111-115), competent cell transformation (see, e.g., Young and Spizizen, 1961, J. Bacteriol. 81: 823-829, or Dubnau and Davidoff-Abelson, 1971, J. Mol. Biol. 56: 209-221), electroporation (see, e.g., Shigekawa and Dower, 1988, Biotechniques 6: 742-751), or conjugation (see, e.g., Koehler and Thorne, 1987, J. Bacteriol. 169: 5271-5278). The introduction of DNA into an E. coli cell may be effected by protoplast transformation (see, e.g., Hanahan, 1983, J. Mol. Biol. 166: 557-580) or electroporation (see, e.g., Dower et al., 1988, Nucleic Acids Res. 16: 6127-6145). The introduction of DNA into a Streptomyces cell may be effected by protoplast transformation, electroporation (see, e.g., Gong et al., 2004, Folia Microbiol. (Praha) 49: 399-405), conjugation (see, e.g., Mazodier et al., 1989, J. Bacteriol. 171: 3583-3585), or transduction (see, e.g., Burke et al., 2001, Proc. Natl. Acad. Sci. USA 98: 6289-6294). The introduction of DNA into a Pseudomonas cell may be effected by electroporation (see, e.g., Choi et al., 2006, J. Microbiol. Methods 64: 391-397) or conjugation (see, e.g., Pinedo and Smets, 2005, Appl. Environ. Microbiol. 71: 51-57). The introduction of DNA into a Streptococcus cell may be effected by natural competence (see, e.g., Perry and Kuramitsu, 1981, Infect. Immun 32: 1295-1297), protoplast transformation (see, e.g., Catt and Jollick, 1991, Microbios 68: 189-207), electroporation (see, e.g., Buckley et al., 1999, Appl. Environ. Microbiol. 65: 3800-3804), or conjugation (see, e.g., Clewell, 1981, Microbiol. Rev. 45: 409-436). However, any method known in the art for introducing DNA into a host cell can be used.

The host cell may also be a eukaryote, such as a mammalian, insect, plant, or fungal cell.

The host cell may be a fungal cell. “Fungi” as used hereincludes the phyla Ascomycota, Basidiomycota, Chytridiomycota, and Zygomycota as well as the Oomycota and all mitosporic fungi (as defined by Hawksworth et al., In, Ainsworth and Bisby's Dictionary of The Fungi, 8th edition, 1995, CAB International, University Press, Cambridge, UK).

The fungal host cell may be a yeast cell. “Yeast” as used herein includes ascosporogenous yeast (Endomycetales), basidiosporogenous yeast, and yeast belonging to the Fungi Imperfecti (Blastomycetes). Since the classification of yeast may change in the future, for the purposes of this invention, yeast shall be defined as described in Biology and Activities of Yeast (Skinner, Passmore, and Davenport, editors, Soc. App. Bacteriol. Symposium Series No. 9, 1980).

The yeast host cell may be a Candida, Hansenula, Kluyveromyces, Pichia, Saccharomyces, Schizosaccharomyces, or Yarrowia cell, such as a Kluyveromyces lactis, Saccharomyces carlsbergensis, Saccharomyces cerevisiae, Saccharomyces diastaticus, Saccharomyces douglasii, Saccharomyces kluyveri, Saccharomyces norbensis, Saccharomyces oviformis, or Yarrowia lipolytica cell.

The fungal host cell may be a filamentous fungal cell. “Filamentous fungi” include all filamentous forms of the subdivision Eumycota and Oomycota (as defined by Hawksworth et al., 1995, supra). The filamentous fungi are generally characterized by a mycelial wall composed of chitin, cellulose, glucan, chitosan, mannan, and other complex polysaccharides. Vegetative growth is by hyphal elongation and carbon catabolism is obligately aerobic. In contrast, vegetative growth by yeasts such as Saccharomyces cerevisiae is by budding of a unicellular thallus and carbon catabolism may be fermentative.

The filamentous fungal host cell may be an Acremonium, Bacillus, Aureobasidium, Bjerkandera, Ceriporiopsis, Chrysosporium, Coprinus, Coriolus, Cryptococcus, Filibasidium, Fusarium, Humicola, Magnaporthe, Mucor, Myceliophthora, Neocallimastix, Neurospora, Paecilomyces, Penicillium, Phanerochaete, Phlebia, Piromyces, Pleurotus, Schizophyllum, Talaromyces, Thermoascus, Thielavia, Tolypocladium, Trametes, or Trichoderma cell.

For example, the filamentous fungal host cell may be an Bacillus awamori, Bacillus foetidus, Bacillus fumigatus, Bacillus japonicus, Bacillus nidulans, Bacillus niger, Bacillus cibi, Bjerkandera adusta, Ceriporiopsis aneirina, Ceriporiopsis caregiea, Ceriporiopsis gilvescens, Ceriporiopsis pannocinta, Ceriporiopsis rivulosa, Ceriporiopsis subrufa, Ceriporiopsis subvermispora, Chrysosporium inops, Chrysosporium keratinophilum, Chrysosporium lucknowense, Chrysosporium merdarium, Chrysosporium pannicola, Chrysosporium queenslandicum, Chrysosporium tropicum, Chrysosporium zonatum, Coprinus cinereus, Coriolus hirsutus, Fusarium bactridioides, Fusarium cerealis, Fusarium crookwellense, Fusarium culmorum, Fusarium graminearum, Fusarium graminum, Fusarium heterosporum, Fusarium negundi, Fusarium oxysporum, Fusarium reticulatum, Fusarium roseum, Fusarium sambucinum, Fusarium sarcochroum, Fusarium sporotrichioides, Fusarium sulphureum, Fusarium torulosum, Fusarium trichothecioides, Fusarium venenatum, Humicola insolens, Humicola lanuginosa, Mucor miehei, Myceliophthora thermophila, Neurospora crassa, Penicillium purpurogenum, Phanerochaete chrysosporium, Phlebia radiata, Pleurotus eryngii, Thielavia terrestris, Trametes villosa, Trametes versicolor, Trichoderma harzianum, Trichoderma koningii, Trichoderma longibrachiatum, Trichoderma reesei, or Trichoderma viride cell.

Fungal cells may be transformed by a process involving protoplast formation, transformation of the protoplasts, and regeneration of the cell wall in a manner known per se. Suitable procedures for transformation of Bacillus and Trichoderma host cells are described in EP 238023, Yelton et al., 1984, Proc. Natl. Acad. Sci. USA 81: 1470-1474, and Christensen et al., 1988, Bio/Technology 6: 1419-1422. Suitable methods for transforming Fusarium species are described by Malardier et al., 1989, Gene 78: 147-156, and WO 96/00787. Yeast may be transformed using the procedures described by Becker and Guarente, In Abelson, J. N. and Simon, M. I., editors, Guide to Yeast Genetics and Molecular Biology, Methods in Enzymology, Volume 194, pp 182-187, Academic Press, Inc., New York; Ito et al., 1983, J. Bacteriol. 153: 163; and Hinnen et al., 1978, Proc. Natl. Acad. Sci. USA 75: 1920.

These detection methods include, but are not limited to, use of specific antibodies, formation of an enzyme product, or disappearance of an enzyme substrate. For example, an enzyme assay may be used to determine the activity of the polypeptide.

The DNase variant polypeptide may be recovered using methods known in the art. For example, the DNase variant polypeptide may be recovered from the nutrient medium by conventional procedures including, but not limited to, collection, centrifugation, filtration, extraction, spray-drying, evaporation, or precipitation. In some aspects, a fermentation broth comprising the DNase variant is recovered.

The polypeptide may be purified by a variety of procedures known in the art including, but not limited to, chromatography (e.g., ion exchange, affinity, hydrophobic, chromatofocusing, and size exclusion), electrophoretic procedures (e.g., preparative isoelectric focusing), differential solubility (e.g., ammonium sulfate precipitation), SDS-PAGE, or extraction (see, e.g., Protein Purification, Janson and Ryden, editors, VCH Publishers, New York, 1989) to obtain substantially pure polypeptides.

Any bleaching system comprising components known in the art for use in cleaning detergents may be utilized. Suitable bleaching system components include sources of hydrogen peroxide; sources of peracids; and bleach catalysts or boosters.

Sources of hydrogen peroxide: Suitable sources of hydrogen peroxide are inorganic persalts, including alkali metal salts such as sodium percarbonate and sodium perborates (usually mono- or tetrahydrate), and hydrogen peroxide-urea (1/1).

Sources of peracids: Peracids may be (a) incorporated directly as preformed peracids or (b) formed in situ in the wash liquor from hydrogen peroxide and a bleach activator (perhydrolysis) or (c) formed in situ in the wash liquor from hydrogen peroxide and a perhydrolase and a suitable substrate for the latter, e.g., an ester.

a) Suitable preformed peracids include, but are not limited to, peroxycarboxylic acids such as peroxybenzoic acid and its ring-substituted derivatives, peroxy-α-naphthoic acid, peroxyphthalic acid, peroxylauric acid, peroxystearic acid, ε-phthalimidoperoxycaproic acid [phthalimidoperoxyhexanoic acid (PAP)], and o-carboxybenzamidoperoxycaproic acid; aliphatic and aromatic diperoxydicarboxylic acids such as diperoxydodecanedioic acid, diperoxyazelaic acid, diperoxysebacic acid, diperoxybrassylic acid, 2-decyldiperoxybutanedioic acid, and diperoxyphthalic, -isophthalic and -terephthalic acids; perimidic acids; peroxymonosulfuric acid; peroxydisulfuric acid; peroxyphosphoric acid; peroxysilicic acid; and mixtures of said compounds.

ATC or a short chain triglyceride like triacetin has the advantage that they are environmentally friendly. Furthermore, acetyl triethyl citrate and triacetin have good hydrolytical stability in the product upon storage and are efficient bleach activators. Finally, ATC is multifunctional, as the citrate released in the perhydrolysis reaction may function as a builder.

Assays and Detergent Compositions Composition of Model Detergent A (Liquid)

Ingredients: 12% LAS, 11% AEO Biosoft N25-7 (NI), 7% AEOS (SLES), 6% MPG (monopropylene glycol), 3% ethanol, 3% TEA, 2.75% cocoa soap, 2.75% soya soap, 2% glycerol, 2% sodium hydroxide, 2% sodium citrate, 1% sodium formiate, 0.2% DTMPA and 0.2% PCA (all percentages are w/w (weight percent)).

Assay A-C Activity of Purified Samples

Before testing the DNase samples for stability in Assay A, B or C they were analyzed for activity according to following procedure. Purified DNAse samples were diluted to 7.5 ppm in a 96 well plate using a dilution buffer (50 mM Tris-HCl, pH7+0.1% Triton X-100) on a Hamilton Nimbus 4 channel liquid handler. A standard curve of DNase (e.g. SEQ ID NO: 1 or SEQ ID NO: 28) at 2.5, 5 and 7.5 ppm was prepared accordingly.

12 μl normalized DNase sample is added to 228 μl Model A and the solution is shaken for 90 s at 2000 rpm (2 mm orbit). 10 μl of the sample is added to 190 μl DNA substrate (3.3 mg/ml Salmon sperm DNA+50 mM Tris-HCl, pH7+5 mM MgCl2+5 mM CaCl2) and the 96 well plate containing the samples and DNA substrate are mixed at 1500 rpm for 90 s (Orbit 2 mm). The plate is incubated for 1 h at room temperature and DNase activity measured according to the procedure: The Hamilton STAR measures the viscosity of the samples and thereby the activity of the DNase using ViPr assay technology as described in (WO2011/107472 A1) by aspirating 100 μI of the assay solution with a standard clear CORE 300 μI tip at a speed of 50 μI/s. The solution is dispensed back to the original well at 10 μI/s and the measurement repeated 5 times. The pressure data during the aspiration step from all of the 96 wells are collected and the pressure value at 1000 ms after start of the aspiration is taken for calculation of the DNase activity in Relative units (RU). Relative units are calculated by division of the buffer value (blank; 1000 ms) by the pressure value (1000 ms) of a given sample subtracted by 1. Samples that show activity below 2.5 ppm compared to the standard curve are adjusted to a level at least >10 ppm and below <20 ppm. All samples are transferred in triplicate to a 96 well plate with a 5 ppm DNase (SEQ ID NO: 1 or SEQ ID NO: 28) sample as reference.

Assay A

The 96 well plate with the normalized DNase samples and a and dilutions of DNase (SEQ ID NO:28) was loaded on the Hamilton STAR robot equipped with a 96 channel TADM head which allows the simultaneous measuring of pressure in the head space of each single pipette channel 12 μl normalized DNase sample is added to 228 μl Model A with Protease (136 ppm). The solution is shaken for 90 s at 2000 rpm (2 mm orbit) and 80 μl of the solution are added to two PCR plates. Plate A (Stress) is incubated at 40° C. and plate B (Reference) at 4° C. for 24 h. Plate A and B are transferred to room temperature. 190 μl DNA substrate (3.3 mg/ml Salmon sperm DNA+50 mM Tris-HCl, pH7+5 mM MgCl2+5 mM CaCl2) is added to 2×96 well plates. 10 μl of sample from plate A and plate B respectively are added to corresponding plates containing DNA substrate. The samples and DNA are mixed at 1500 rpm for 90 s (Orbit 2 mm) and incubated for 1 h at room temperature. The Hamilton STAR measures the viscosity using ViPr assay technology as described in (WO2011/107472 A1) by aspirating 100 μI with a standard clear CORE 300 μI tip at a speed of 50 μl/s. The solution is dispensed back to the original well at 10 μl/s and the measurement repeated 5 times. The pressure data during the aspiration step from all of the 96 wells are collected and the pressure value at 1000 ms after start of the aspiration is taken for calculation of the DNase activity in Relative units (RU). Relative units are calculated by division of the buffer value (blank; 1000 ms) by the pressure value (1000 ms) of a given sample subtracted by 1. Relative activity (RA) is calculated by

${{Residual}\mspace{14mu} {Activity}\mspace{14mu} (\%)} = {\frac{{RU}_{variant}}{{RU}_{reference}}*100}$

Assay B

Conditions and activity determination of DNase variants as described in Assay A except that DNAse samples were exposed to Model A detergent+0.4% K2503 for 1 hour at 60° C. The detergent solution is prepared by mixing Model A (50 g) with 0.2 g K2503 for 1 h under vigorous stiring.

Assay C

Conditions and activity determination of DNase variants as described in Assay A except that DNAse samples were exposed to Model A detergent alone for 2 hours at 62° C.

Residual activity ratio (RAR)

The residual activity ratio for each condition was calculated by using an stabilizied variant as reference. The variants were tested in 3 conditions described above and the RAR calculated by using the following formula:

${{Residual}\mspace{14mu} {Activity}\mspace{14mu} {Ratio}\mspace{14mu} ({RAR})} = \frac{{RA}_{variant}}{{RA}_{reference}}$

General methods of PCR, cloning, ligation nucleotides etc. are well-known to a person skilled in the art and may for example be found in “Molecular cloning: A laboratory manual”, Sambrook et al. (1989), Cold Spring Harbor lab., Cold Spring Harbor, N.Y.; Ausubel, F. M. et al. (eds.); “Current protocols in Molecular Biology”, John Wiley and Sons, (1995); Harwood, C. R., and Cutting, S. M.

Higgins eds (1985); “A Practical Guide To Molecular Cloning”, B. Perbal, (1984).

EXAMPLES Example 1: Construction of Variants by Site-Directed Mutagenesis

Site-directed variants were constructed of the Bacillus cibi DNase (SEQ ID NO: 1), comprising specific substitutions according to the invention. The variants were made by traditional cloning of DNA fragments (Sambrook et al., Molecular Cloning: A Laboratory Manual, 2nd Ed., Cold Spring Harbor, 1989) using PCR together with properly designed mutagenic oligonucleotides that introduced the desired mutations in the resulting sequence.

Mutagenic oligos were designed corresponding to the DNA sequence flanking the desired site(s) of mutation, separated by the DNA base pairs defining the insertions/deletions/substitutions, and purchased from an oligo vendor such as Life Technologies. To test the DNase variants of the invention, the mutated DNA comprising a variant of the invention are integrated into a competent B. subtilis strain by homologous recombination, fermented using standard protocols (yeast extract based media, 3-4 days, 30° C.), and screened by activity assay.

The constructed variants were plated on LB agar supplemented with 6 ug/ml chloramphenicol and grown for 37° C. for one day. After growth, colonies were picked to individual wells of standard 96-well microtiter plates containing 200 ul TBgly broth supplemented with 6 ug/ml chloramphenicol and trace metals (50 mM FeC13, 20 mM CaCl2, 10 mM MnCl2, 10 mM ZnSO4, 2 mM CuCl2, and 2 mM NiCl2, (F. William Studier, “Protein production by auto-induction in high-density shaking cultures”, Protein Expression and Purification, 41 (2005) 207-234).

The wild type Bacillus cibi DNase, was also inoculated as reference in four wells on each microtiter plate. The microtiter plates were grown for three days at 30° C. with shaking at 220 rpm. After growth, the supernatants were screened for residual activity after stressing them for 20 minutes at 48.5° C. in the presence of 96% (v/v) Model A.
